This application claims the priority benefit, under 35 U.S.C. § 119, of Korean Patent Application No. 20-2017-0004045, filed on Aug. 1, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The following description of example embodiments relates to racks having scalability and compatibility.
A rack that is a basic platform in, for example, a server room such as a data center is a device configured to store and maintain computerized equipment (e.g., a server rack). For example, Korean Registered Utility Model Publication No. 20-0207329 discloses a server rack, where the server rack is easily transportable and installable due to a main frame constituting the rack being detachably assembled to a top plate and a lower plate.
Racks with various sizes, for example, a 16-inch standard rack and a 21-inch rack, are available based on a size of computerized equipment that such racks are configured to accommodate. In addition, such racks may be configured to use and/or support various power supply schemes, for example, alternating current (AC) 220V of main power or direct current (DC) power for additional power supply.
However, in the case of the racks according to the related art, for example, a first rack configured to support equipment having a first size (e.g., a 19-inch rack) may need to be one-to-one replaced with a separate rack that is configured to support equipment having a second, larger size (e.g., a 21-inch rack) in order to provide a second rack configured to support equipment having the second, larger size where the first rack is not configured to support equipment larger than the first size and the larger rack is not configured to support equipment smaller than the second size. Also, if a rack does not support a specific desired power supply scheme, the rack may need to be replaced in order to provide a rack configured to support the specific desired power supply scheme.
At least one example embodiment provides a scalable or compatible rack that may be scalable, progressively and/or inversely, between accommodating (also referred to interchangeably herein as “storing,” “supporting,” “structurally supporting,” or the like) computerized equipment of various sizes (e.g., equipment having at least one dimension, including length, width, depth, and/or height, that has various sizes); for example, the rack may be scalable between having a standard 19 inch size (e.g., defining an interior volume having a 19-inch width) to be configured to accommodate 19-inch equipment (e.g., equipment having a 19-inch width) and having a standard 21 inch size (e.g., defining an interior volume having a 21-inch width) to be configured to accommodate 21-inch equipment (e.g., equipment having a 21-inch width).
At least one example embodiment also provides a rack that is compatible between (e.g., configured to reversibly switch between supporting) an alternating current (AC) power supply scheme (e.g., based on being configured to accommodate (also referred to interchangeably herein as “store,” “support,” “structurally support,” or the like) AC power supply equipment in a particular interior volume that is at least partially defined by one or more elements of the rack) and a direct current (DC) power supply scheme e.g., based on being configured to accommodate DC power supply equipment in a particular interior volume that is at least partially defined by one or more elements of the rack).
According to at least one example embodiment, a rack configured to support computerized equipment may include a main frame configured to structurally support computerized equipment having a particular dimension that is a first size within an enclosure that is a first enclosure at least partially defined by the main frame. The rack may include at least one additional frame configured to reversibly couple with the main frame to adjust the enclosure to be a second enclosure at least partially defined by the at least one additional frame to reversibly configure the main frame to store computerized equipment having the particular dimension that that is a second size that is different from the first size.
The first size may be greater than the second size.
The first size may be 21 inches and the second size may be 19 inches.
The at least one additional frame may include four additional frames configured to couple with separate, respective corner portions of four corner portions of the main frame that define four corner portions of the enclosure.
The at least one additional frame may be configured to fasten to the main frame based on coupling a hole included in the at least one additional frame and a corresponding hole of the main frame via a bolt and a nut.
The at least one additional frame may include at least one hook that is configured to be fixably extended through a hole of the main frame.
The main frame may include a coupler configured to fasten the at least one additional frame based on a shape of the at least one additional frame.
The rack may further include a rear frame configured to at least partially define a rear enclosure configured to support a direct current (DC) rectifier module, wherein at least a portion of the rear frame includes a mesh configured to support cable management.
The at least one additional frame may be an individual frame.
The main frame may include a plurality of coupling points, and the at least one additional frame may be configured to couple with at least one coupling point of the plurality of coupling points to be reversibly coupled with the main frame.
According to at least one example embodiment, a method may include providing a main frame, the main frame including one or more structural elements defining an enclosure that is a first enclosure within an outer volume boundary of the main frame, such that the main frame is configured to store computerized equipment having a particular dimension that is a first size within the first enclosure. The method may include reversibly coupling at least one additional frame with the main frame to adjust the enclosure to be a second enclosure at least partially defined by the at least one additional frame to reversibly configure the main frame to store computerized equipment having the particular dimension that that is a second size within the second enclosure, the second size different from the first size.
The first size may be greater than the second size.
The first size may be 21 inches and the second size may be 19 inches.
The reversibly coupling the at least one additional frame may couple four additional frames with separate, respective corner portions of four corner portions of the main frame that define four corner portions of the enclosure.
The reversibly coupling the at least one additional frame may fasten the at least one additional frame to the main frame based on coupling a hole included in the at least one additional frame and a corresponding hole of the main frame via a bolt and a nut.
The reversibly coupling the at least one additional frame may fixably extend at least one hook of the at least one additional frame through a hole of the main frame.
The main frame may include a coupler configured to fasten the at least one additional frame based on a shape of the at least one additional frame.
The method may further include providing a rear frame to at least partially define a rear enclosure configured to support a direct current (DC) rectifier module, wherein at least a portion of the rear frame includes a mesh configured to support cable management.
The at least one additional frame may be an individual frame.
The main frame may include a plurality of coupling points, and the reversibly coupling the at least one additional frame may couple the at least one additional frame with at least one coupling point of the plurality of coupling points to be reversibly coupled with the main frame.
These and/or other aspects, features, and advantages of at least one example embodiment will become apparent and more readily appreciated from the following description of at least one example embodiment, taken in conjunction with the accompanying drawings of which:
One or more example embodiments will be described with reference to the accompanying drawings. Advantages and features of the one or more example embodiments, and methods for achieving the same may become explicit by referring to the accompanying drawings and the following one or more example embodiments. At least one example embodiment, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated one or more example embodiments. Rather, the illustrated one or more example embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art. Accordingly, known processes, elements, and techniques, may not be described with respect to at least one example embodiment. Unless otherwise noted, like reference characters denote like elements throughout the attached drawings and written description, and thus descriptions will not be repeated.
When an element or a layer is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to,” another element or layer, the element or the layer may be directly on, connected to, coupled to, or adjacent to, the other element or layer, or one or more other intervening elements or layers may be present (e.g., when an element or a layer is referred to as being “indirectly on,” “indirectly connected to,” “indirectly coupled to,” or “indirectly adjacent to,” another element or layer). In contrast, when an element or a layer is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to,” another element or layer, there are no intervening elements or layers present. An element that is “on” another element may be “above” or “underneath” the other element.
Although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections, should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section, from another region, layer, or section. Thus, a first element, component, region, layer, or section, discussed below may be termed a second element, component, region, layer, or section, without departing from the scope of this disclosure.
As used herein, equipment may have a “standard size” and/or a rack may be configured to support equipment having a standard size, such that the rack may be referred to as being of the standard size. As referred to herein, a “standard size” with regard to computerized equipment and/or a rack may refer to any Electronics Industries Alliance (EIA) standard, Consumer Electronics Association standard, International Electrotechnical Commission standard, some combination thereof, or the like. For example, a 19-inch rack as described herein may be a rack having a frame and/or interior space (“enclosure”) that is configured to store computerized equipment having a standard 19-inch size under the EIA standard EIA-310-D for 19-inch standard sizes. In another example, a 21-inch rack as described herein may be a rack having a frame and/or interior space (“enclosure”) that is configured to store computerized equipment having a standard 21-inch size under the European Telecommunications Standards Institute (ETS 300 119), or ETSI rack standard, for 21-inch standard sizes.
Here, the first size may be greater than the second size. For example, the first size (e.g., of a width dimension) may be 21 inches and the second size (e.g., of the same width dimension) may be 19 inches. Racks according to an international standard for 19-inch equipment may have the same width of 600 mm and may have a depth of, generally, 750 to 800 mm. In general, a rack for 21-inch equipment (“a rack configured to store 21-inch equipment”) is configured to have a width of 700 mm. It will be easily understood that the first size and the second size or a difference between the first size and the second size may be variously set based on sizes of electronic equipment to be stored in the rack 100.
As shown in
The rack 100 may include, in addition to the main frame 110, one or more additional frames that may be reversibly coupled with the main frame to adjust one or more dimensions, and thus the size of, the enclosure defined within the outer volume boundary 111 of the structure of the rack 100, so that the enclosure may be reversibly adjusted between various sizes that are configured to accommodate equipment having various sizes (e.g., one or more particular dimensions having various sizes) without adjusting the outer volume boundary 111 of the structure of the rack.
Accordingly, based on being configured to enable reversibly coupling of one or more additional frames 120 to one or more portions of the main frame 110, the rack 100 is configured to support computerized equipment of various sized, and thus support reversibly changing between supporting computerized equipment of various sizes, without requiring replacement of the entire rack 100 for a separate rack (e.g., a rack having different outer volume boundaries 111) that is configured to support a different size of computerized equipment. Such a configuration of the rack 100 may be referred to herein as “scalability,” in that the rack 100 is configured to “scale” between accommodating different sizes of computerized equipment without replacement of the rack 100 or modification (“adjustment”) of the outer volume boundary 111 of the structure of the rack 100. Such scalability may reduce costs and/or expenditures associated with maintaining and/or operating a data center wherein the rack 100 is installed, as the rack 100 may be configured to “scale” between supporting different sizes of equipment without requiring replacement or modification of the outer volume boundary 111 of the rack 100, thereby mitigating replacement or re-arrangement of one or more racks 100 in the data center. In addition, because a single type of rack 100 may be included in the data center to support a range of sizes of computerized equipment, instead of utilizing multiple various different sizes of racks, capital costs associated with racks 100 may be reduced and rack configurations in a data center may be more efficient at least by virtue of avoiding configurations of differently-sized racks and instead promoting the use of configurations of uniformly-sized racks 100.
According to at least one example embodiment, including the at least one example embodiment shown in
According to at least one example embodiment, the rack 100 for the first size may be compatible with, for example, transformable, “scalable,” or the like, to be configured to reversibly adjust one or more dimensions of (e.g., the “size” of) the enclosure 210 between a first, larger-sized enclosure 210-1 and a second, smaller-sized enclosure 210-2 based on being configured to enable one or more additional frames 120 to be coupled in the main frame 110 of the rack 100 (where the main frame 110 defines enclosure 210-1) to at least partially define enclosure 210-2 based on limiting an inner width W of the enclosure 210 of the rack 100. In another example, the rack 100 for the second size may be scalable, for example, expandable between a second size and a larger first size based on removing the additional frames 120 from the rack 100 to expand the enclosure 210 from the second, smaller enclosure 210-2 at least partially defined by the additional frames 120 to the first, larger enclosure 210-1 at least partially defined by the main frame 110. Restated, the one or more additional frames 120 may be reversibly (“detachably,” “removably,” or the like) coupled with the main frame 110 to reversibly scale (transform, expand, or the like) the rack 100 between being configured to store equipment having various sizes without altering the outer volume boundary 111 of the rack 100. Accordingly, the rack 100 may be configured to enable various sizes of equipment to be stored therein over time without requiring a replacement of the rack or adjustment of the outer volume boundary of same, thereby enabling reduced capital and maintenance expenditures associated with rack placement, installation, ordering, management, maintenance, some combination thereof, or the like. As referred to herein, reversibly configuring the rack 100 to store computerized equipment having one or more various particular dimensions having one or more particular sizes, e.g., based on reversibly coupling one or more additional frames 120 to one or more coupling points of main frame 110, may be referred to as reversibly configuring the main frame 110 to store computerized equipment having one or more various particular dimensions having one or more particular sizes.
One of ordinary skill in the art may easily understand that various schemes may be used to attach or detach the main frame 110 and the additional frames 120. For example, the main frame 110 may include a coupler configured to fasten one or more frames of the additional frames 120 relative to the main frame 110. As another example, the main frame 110 may include a hook, such as at least one hook, that enables the additional frames 120 to be fastened through (e.g., extended through) one or more holes included in the main frame 110. As another example, the main frame 110 and the additional frames 120 may be configured to couple with each other through corresponding holes included in the main frame 110 and the additional frames 120 using bolts and nuts.

Still referring to
As referred to herein, equipment and/or racks “of” a given size, “having” a given size, or the like will be understood to be associated with and/or having at least one particular dimension that is the given size (e.g., a width of 19 inches).
The rear space (“enclosure 810”) of the rack 100 may be configured to be used as a space for installing (e.g., configured to “accommodate,” “store,” “support,” structurally support, or the like) a direct current (DC) rectifier module (“assembly”) that is configured to supply DC power to computerized equipment supported within enclosure 210 or as a space for applying (e.g., configured to “accommodate,” “store,” “support,” structurally support, or the like) a bus duct of over current protection (OCP) DC power. Since the DC rectifier module (“DC rectifier assembly”) is provided (“included,” “accommodated,” “stored,” “supported,” “structurally supported,” or the like) in the rear space (enclosure 810) of the rack 100, it is possible to supply alternating current (AC) 220V as main power to at least some computerized equipment accommodated in enclosure 210 and to, at the same time, supply DC power through the DC rectifier module to at least some computerized equipment accommodated in enclosure 210. That is, various power supply schemes may be available. Restated, the rack 100 may be configured to support various power supply schemes for computerized equipment accommodated in enclosure 210, including supporting different power supply schemes simultaneously, based at least in part upon being configured to support at least one DC rectifier module in enclosure 810 and/or a bus duct of over current protection (OCP) DC power at least partially in enclosure 810. Accordingly, based on being configured to simultaneously support computerized equipment with various, different power supply schemes, the rack 100 may enable reduced capital costs and maintenance costs based on enabling a single rack and/or type of rack to be used to support multiple various power supply schemes and to further enable computerized equipment utilizing different power supply schemes to be supported by a single, common rack 100. Also, a mesh-type net 710, also referred to herein as simply a “mesh,” configured to support cable management may be included in rack 100 to at least a portion of a rear frame portion 850 of main frame 110 that constitutes (“at least partially defines”) the rear space of the rack 100. The rear frame portion 850 of the main frame 110 may be referred to herein as a “rear frame” of rack 100 and may include a portion of the structural elements of main frame 110, including interposing structural elements 802, which collectively define the rear enclosure 810, separately from the portions and/or structural elements of the main frame which collectively define at least enclosure 210-1 of enclosure 210.
Also, referring to
In at least one example embodiment, the additional frame 120 may couple with the main frame 110 using a bolt and a nut instead of using the hook 1010. In at least one example embodiment, the main frame 110 may include a coupler configured to fasten the additional frame 120 based on a shape of the additional frame 120. Here, the additional frame 120 may couple with the main frame 110 by inserting into the coupler. For example, the main frame 110 may include a coupling that is a hook element and/or hole that has a particular shape and/or position on one or more structural elements of the main frame 110, such that the coupler is specifically configured to couple with an additional frame based on the additional frame having a first particular shape and is further configured to be restricted from coupling with one or more additional frames based on the one or more additional frames having one or more second particular shapes that are different from the first particular shape.
Referring to
Accordingly, it is possible to provide a scalable function or a compatible function, for example, from 19 inches to 21 inches or from 21 inches to 19 inches, using a single rack, and to enable the rack to be compatible between an AC power supply scheme and a DC power supply scheme.
As shown in
A number of example embodiments have been described above. Nevertheless, it should be understood that various modifications may be made to these example embodiments. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
